Back from the dead!



All Hallow's Eve approaches and many friends are telling me that they are feeling like death warmed up.
It is normal to be worn down by fatigue and and moan that this is a horrible time of year. We wish all these stomach bugs and infections on our chests would go away...and quickly.
I am also “full of cold”, falling in to a deep exhausted sleep for hours at a time, and struggling to write through an aching body and head which has continued for a week. But I am excited and happy about this.

Why??? Why would I be so perverse?
To shorten a difficult explanation: because it is a sign that my body is alive and kicking!

You see, I have now been through years of these phases of increased immune response with aching bones, upset stomach, mucus-production, sinusitis and headaches. I made them happen by embarking on a radical and tough immune-stimulating drug protocol called the Marshall Protocol. This is the opposite of many mainstream immune-suppressing medical treatments for chronic pain and autoimmune conditions.

The result after 17 months has been a huge reduction in my chronic pain, diagnosed as fibromyalgia, and the recovery of my ability to maintain a stable body temperature (At times in the past three to five years the number of clothing layers I needed was ridiculous and any exposure of my skin to cooler air led to uncontrollable shivering and blueish nails).

I am now able to think about working again because the cognitive dysfunction I experienced for a few years seems to be lifting gradually like a curtain.
I fully expect to face more ups and downs during my recovery, but now I sense that my body can basically cope with what is thrown at it.

In the last month or two I was feeling quite good, sailing along, no longer struggling to walk more than short distances, and able to use my muscles more often without post-exertion pain.
I consulted my two doctors and we agreed that I would make a certain medical adjustment which they predicted would cause my immune response to increase again. This is sometimes called a Herxheimer reaction. We all felt that I was ready for this next step change.

Hence I am now sneezing, coughing, aching and trying to clear my poor sinuses.....and I am rejoicing as I take the next steps in my recovery! I haven't “caught a bug” - my body is responding exactly as planned, to control the chronic infections already at home inside my body.

I want to write a whole series of blog posts about natural immune responses of different types (subject to my own daily symptoms!). If you don't think I am explaining in a lot more depth what I believe is happening in the body, contact me and tell me!

Good health everyone!

Are humans bigger mice without tails?



I have been sighing a lot over my laptop lately as a plethora of research these days claims that scientists could soon protect the whole of human kind from this disease or that disease.....on the basis of experimentation on mice.
One example is this reported in ScienceDaily which states: "The immune system of mice is very similar to that of humans".


I'm sorry but I cannot accept this bland statement. So often when I check the research papers, the researchers refer to the adaptive immune system (the one that recognises particular pathogens and then attacks) as if this is the only one there is.


In addition to the skin, the other layer of protection for the body is the innate immune system. This offers a constant and universal defence against dangers presented by microbes in the body. It is permanently on stand-by and can react to anything within seconds, sending a change along hundreds of response pathways.


The innate system consists of a variety of relatively little-researched receptors embedded in to the cells of our body. Some of these are called Toll-like receptors (TLR).


It is now known that humans - but not mice - have TLR10, plus mice have the additional TLRs 11, 12 & 13. Also the working of TLR8 is different in humans, compared with mice. 
I wish scientists would stop publishing papers that raise false hopes when clearly there is a big difference between the two mammals.


We may need increased research on fruit flies, not mammals, in my opinion. Yes! According to NASA scientists "Genetically speaking, people and fruit flies are surprisingly alike. About 61% of known human disease genes have a recognizable match in the genetic code of fruit flies, and 50% of fly protein sequences have mammalian analogues."
And they seem perfect for researching the little-known innate immunity pathways since fruit flies have no adaptive immune system.
Knowing these facts, I wonder if I could evolve a tail in the time that current pharmaceutical-based research can come up with human disease cures based on mouse models. Sorry to sound pessimistic, but I wish research money was directed in to more helpful avenues.

Coalition thinking


Wow, what a week it's been for the English! Our first exciting experience of creating a real political coalition.
For it to continue, and work effectively, I believe we will have to change ourthinking. Maybe in the same way that microbiology experts have had to change their thinking recently about the human body and why it gets ill.
For so long we have talked of a sealed and protected physical body that has to wage war against any pathogens that threaten to infect us from the outside.
At the same time people have started to understand now that there are a lot of friendly bacteria on the inside (mainly because of that advert for a certain mini-drink).

So here we have a model depicting two tribes of bacteria, which suits our traditional way of thinking:there are these friendly, helpful bacteria that understand the needs of the human body; and there are those BAD bacteria (boo!) that we must never allow to have control over our body.
Suddenly we have a new third set of bacteria being mentioned and people are starting to say "D'you know, I never realised that they could look like that, or how they work exactly?" A bit like Nick Clegg.

Some microbiologists have named these bacteria existing inside our bodies pathobionts - a combination of pathogen and symbiont. A symbiont is a helpful organism which works in perfect synergy with its host.
Other experts are describing the human body now as a "superorganism" and conclude that the newly discovered microbes provide "metabolic functions far beyond the scope of our own physiological capabilities".
So how can we be sure if these pathobionts are going to work well together for our good, or if they might harm us instead?

We simply can't be sure.
That's right, we just have to try to get along with them.
We have to provide the right structure to work together in our body (a healthy immune system, well exercised muscles).
We have to limit the jobs that they do in our body to the ones we want them quietly to get on with (by not overfeeding them with any processed foods).
And we have to promise that we won't suddenly attack their tribal group (antibiotics are a dangerous weapon).

We are going to have to learn to live and work together with our pathobionts, otherwise we will see an even greater increase in chronic illness than we have already.
If you think my analogy is a bit far fetched then have a look at this scientific article (which focuses particularly on fungal infections like candida). University of North Carolina microbiologist William E. Goldman says that the infections are "not very good at causing disease in normal hosts with normal immune systems".
"But a growing population of people have not-so normal immune systems. Fungal infections are so deadly in part because most patients who become seriously ill are already weakened by AIDS, cancer, transplants or medications that handicap the body’s ability to mount a strong defense.
"More and more of these patients have taken high doses of anti biotics to prevent other infections, fundamentally changing the body’s ecology and allowing unnatural fungal growths to take over. More patients are also undergoing medical procedures that breach normal immune barriers with catheters and other devices."
He mentions catheters because we all have three parts to our immune system: the largest organ in our body, our skin; then our innate immune system which provides 24/7 security guards; and our adaptive system which attacks when danger is identified.
In these interesting times please give the microbial coalition a chance - a strong and stable agreement is the best option for your body's long term health.

Does your brain feel ill?


When we have been ill for a little while it is natural to feel "down", isn't it?
A bout of sickness, flu, or a bad flare-up of our chronic symptoms will often lead to feelings of lethargy and depression and we usually find our fellow humans' response to this is: "That's not surprising after being unable to do things normally - I would get depressed about it too!"
But this is a strange Western rationalisation of the brain as separate from the body. Obviously the brain is actually connected to the body, and the brain tissue can become ill as well.
New research has shown clearly that our brains actually respond to infection in the body to make us FEEL ill; it is not just a psychological after-effect of a physical event - the brain makes this happen.

Now some clear research studies have shown the process involved. The innate (initial defensive) immune system produces proteins called cytokines whenever they encounter a bacterial challenge.
This then signals to the brain, then the entire balance of "mini" hormones and different chemicals in the endocrine system undergoes a change. These signals run through the neurotransmitters and alter our mood and behaviour.
There is already enough evidence to show that the root of depression is in something called the subgenual cingulate of the brain.
When researchers watched the subgenual cingulate with an MRI scanner they found that patients who had mild inflammation from a typhoid injection showed activity here. And those who had the largest inflammatory cytokine response had the greatest problems with their mood and a slowing down of their normal responses.

Dr Neil Harrison of Sussex University told the World Service's Healthcheck programme that many different illnesses with a bacterial element and immune response cause this real physical action in the brain:"Cytokines can cross the blood brain barrier but can also bind to nerve endings and be signalled in the brain."

One thing he didn't touch on was why the body might want the brain to make it feel so bad. If your body feels confused, withdraws from social situations, suffers depression and slows right down, according to this research, that's because it is busy mounting an immune response to infection.
So, may I suggest, it might at times be healthy (for all concerned) to stay at home in bed and avoid others, instead of taking some tablets and making a psychological effort to get back in to the swing of things.

Why am I so tired?!



Everyone's saying it at the moment. Everyone's feeling it. Why?
Hibernation is often the next word out of our mouths – we so envy the squirrels and badgers as they curl up in the warm, and we moan at our bosses for not letting us stay under the duvet each morning.
As autumn and winter set in we seem to be torn over which is the more natural response. Shall we give in to our body's desire for more rest? Or seek more of the natural substances which we believe are good for us (sunshine, vitamin pills, fresh fruit and vegetables) so our bodies can keep active as we aim for a healthy life?
A big factor at this time of year is the number of apparent viruses and infections. We refer to these as bugs 'going round' and comment that we have 'caught' something.
We say we can't 'shake off this chest infection', or we have 'passed our cough on' to another member of the family.
There is no doubt that microbes are very efficient at getting from one human host to another through coughing, sneezing or hands. Yet microbiologists are now beginning to understand that bacteria and viruses can sometimes hang around in all sorts of places in our body without the immune system showing signs of responding at all.
Admittedly a few factors in infectious transmission involve the weather – low temperatures and a low total moisture content of the air create ideal conditions for flu viruses to attach themselves to the mucus-producing surfaces of the body (often the nasal passages).

Research is beginning to show that our immune systems are not always under sudden threat of overwhelming attack when our bodies respond. Our immune systems may instead have 'woken up' to a danger that is already present.
But why might our immune systems go to sleep until then? Surely they are on guard all the time? (See my first blog post for one suggested reason).
A simplified summary of our complex immune response splits it in to two main parts: the innate immune system, which is not yet well understood but involves receptors mounting a standard defence; and the adaptive immune system, where the different types of white blood cells recognise invading pathogens, attack and destroy them.
A healthy immune response in a human body will, once it is fully aware of the danger, rush to remove it. The results of this process can be high temperature, production of mucus, fatigue, inflammation, vomiting, coughing or skin outbreaks – anything to help the body kill off or expel the bacteria.
Does that seem strange to associate these awful symptoms with being 'healthy' internally? Our bodies do so much without us knowing anything about it and scientists are beginning to note that these apparently undesirable symptoms can be helpful, natural responses that keep us healthy.

So, what about times when we only feel tired?
Sleep is an amazingly mysterious thing that is still the focus of much research. But there is already evidence that sufficient sleep contributes to our immunity, and that infection can cause disruption of normal sleep patterns.
Even though nothing else is apparent, I would suggest that tiredness means the body is hard at work doing something that comes naturally. We can't all be subject to close medical scrutiny to find out what is going on inside us at that moment when we collapse on the sofa.

Our first urge when we are fatigued or our bodies seem 'under the weather' is to take away the symptoms and pain. But a lot of commonly used medicines like anti-inflammatories, anti-depressants and prescription steroids actually reduce the functioning of the immune system.
Don't let your immune system go to sleep. Maybe you should give your whole body an early night.
But your boss won't be pleased if you just pull the duvet back over your head each morning.

A modern parable for the chronically ill

A security guard is sitting at his desk, a couple of token CCTV screens in front of him. In this very quiet building the security desk is tucked to one side, away from the gaze of people passing by.
Not much happens so it is unsurprising that occasionally the bored security guard puts his feet up and nods off.
On one of these occasions some brazen robbers take advantage of his nap and creep past the desk. They invade the inner office and tie up the staff.
They steal everything they can get their hands on and get access to the valuables in the safe - but the security guard is none the wiser.

Once the robbers have stolen everything and decided to set up their own illegal business there, they are a bit hungry. They call up a pizza firm and a bakery and impersonate the office manager to order some take-aways.
The pizzas and doughnuts arrive, but the security guard doesn't think this is suspicious and lets the delivery men deliver to the inner office.
The robbers are enjoying their new crime base and the free facilities but eventually get fed up with having to fool the security guard outside in the lobby. So they devise a way of sealing up the security guard's mouth.
Once they have attacked him, he is forced to remain at his desk as if he is on guard, but all he can do is shriek and groan through his sealed mouth. Now the security guard is aware of what’s happening but unable to tell anyone.

He is a conscientious guy so he decides to risk contacting the main security centre to call for help. But at the other end of the phone line the operator is alarmed and confused to receive several calls and hear nothing but a terrible moaning sound.
The security centre operators become quite distressed when the muffled screeches are repeated over and over again as the security guard keeps phoning.
Eventually the controller of the security centre takes a decision to stop these calls that are distressing his staff so much. He sends round a telephone engineer to the nearest exchange.

Soon the telephone line to the office security guard has been cut and they are no longer troubled by the awful calls.
They assume that the office staff and valuables are safe but the security centre has in fact let the robbers get away with the crime. The business originally operating from that sleepy office is now totally wiped out.

Have you noticed how modern Western medicine is devoted to describing what your main symptoms are and then prescribing specific medication to reduce or stop each symptom?
But consider the word ‘symptom’. When we experience pain or joint aches or digestive problems, what are these symptoms of?
Our bodies are complex organisms able to send us messages to tell us that something is wrong. If we remove these messages – these symptoms – then we don’t know anything dangerous is happening.
The security guards in our body are called Vitamin D Receptors. These form the major part of the body’s innate immune system. This is different from the adaptive immune system which moves to destroy any bacterial or viral ‘robbers’.
In our nice clean society the Vitamin D Receptors get sleepy because they don’t have much danger to look out for. But there are some very clever bacterial ‘robbers’ out there who know how to get past them.
Around one hundred of them can fit inside one human cell. They also produce a ‘slime’ which eventually can coat the Vitamin D Receptors and stop them communicating.

If your body seems to be sending you alarming and painful messages – symptoms - then it may be better for your long term health to listen to them, rather than cut them off at source with medication.
For that you don’t need a specialist. You need to have a holistic view of how the body works. In the past this may have been an area left to ‘alternative’ medicine but now some scientists are beginning to uncover how the body works as a whole mesh of complex metabolisms.
Why not make some further investigations to help yourself out of chronic illness and back in to health?
